Psychology students (N = 996) were instructed to record in an informal sleep diary--the time they went to bed, the time they awoke, and the time they set the alarm--over a period of either 5, 7, 10, 20, or 25 nights in an attempt to measure sleep length among a college student population. The average amount of sleep among our participants was 7.69 hr, approximating another study (Kripke, Garfinkel, Wingard, Klauber, & Marler, 2002) which found an average sleep length of 7 hr.
